Note 28 — Chapter XI · A FEW MISCELLANEOUS OPERATIONS

In making the plans for a boat, three views are usually drawn, known as the sheer plan, the body plan, and the half-breadth plan. These correspond to the "front or side elevation," "end elevation," and "plan" in ordinary drawings, and give side, end, and top views of the boat,—or of one-half of it, which is all that is needed, as the sides are of course alike. Several equidistant horizontal lines are drawn across the plans. One of these represents the line of the water when the boat has its proper load. It is called the load water-line. The other lines being parallel to it represent other imaginary levels, at equal distances apart—like the lines which would be made by the water if the boat sunk deeper or floated higher. Other lines are also added to show vertical and horizontal, longitudinal and cross-sections, at regular intervals, and also other longitudinal sections, but these details you will find fully described in works on yacht-(and model yacht-) building.
